EPA Zone 1

Located in Marion County in central Iowa's glaciated prairie region, Hamilton sits in zip code 50116 where radon testing data remains limited. The area's deep glacial till deposits over limestone bedrock create conditions favorable for radon accumulation in the many homes with full basements typical of rural Iowa communities.
